Samsung announces new 50MP ISOCELL GN2 camera sensor with Dual Pixel Pro

23 February 2021
The green pixels are split diagonally to receive information on the top and bottom of the pixel as well.

Sort by:

sounds good! a 3:2 sensor could have been better!! we have seen a 1" sensor in a mobile phone also (Panasonic Lumix Smart Camera CM1), so this one is not the largest

Now they need to bring back their dual aperture lens, otherwise the plane of focus would be too narrow.

But when I saw the Vivo X50 Pro+ review on this site, I'm not sure if I would believe that. I personally found that the manually downscaled photo shows better detail than the pixel binned photo. It's the same story when I saw the Huawei Mate 40 Pro photos - the pixel-binned 12.5 MP produced less noise than the unbinned 50MP, even when manually downscaled to the same pixel binned resolution.

The only time where I saw both pixel binned and native unbinned photo produce exactly the same photo quality is on Xiaomi phones. It really doesn't make any difference if I manually downscaled the unbinned photo, it just looks exactly the same as pixel binned photo.

With that said, as I already mentioned earlier, there are still too many variables to draw a conclusion that QB is inherently slower than a regular Bayer sensor by a significant degree. A fair, direct comparison would've been much easier if Sony or Samsung release two variants of the same sensor, but I guess there would be no point for them to do so when the QB variant obviously would be so much more versatile.

The bayer is taking advantage of the many pixels in the first place hence why 50mp is the sweet spot now


Getting BINNED down to 12 is completely different than just straight up regular 12

Not only that, we don't even know if those two sensors are built on the same generation technology. There are too many variables here, no direct comparison is possible.

Ice Universe claimed that GN2 will be used in Xiaomi Mi11 Ultra

React 2 Gadgets YT, 23 Feb 2021It has RYYB filter which takes in 40% more light. Which mea... moreIt takes in 40% more light PER EXPOSURE, and that's only for yellow pixels. Red and blue will be noisier unless you're in extreme low light due to the fact that the sensor needs to expose for more light sensitive yellow pixels which in turn reduces the light intake for red and blue pixels. Having to interpolate the value for green using yellow and red means it will be never as colour accurate as a comparably sized RGB sensor, too.

The sensor isn't capable of shooting photos at ISO 409600, by the way. Fixing the shutter speed at 1/4s, the exposure of ISO 6400 shots and ISO 204800 shots from my P30 are pretty much the same, though the latter is visibly less noisy and more detailed because Huawei activates a auto "night mode" which shoots lots of frames in burst and combine them together to reduce noise. The crazy-high number you're seeing is just an extended, or simulated ISO, not a max ISO that is supported by the sensor.

Finally, your calculation for the pixel pitch is completely off.

I definitely wouldn't buy into this kind of belief. Computational software is not everything. The M43 can still beat software-focused smartphones when you give an M43 camera a lens with well-built glass optics. You have to remember that there are certain components that software cannot change. Sensors and optics are built as hardware in the first place - if you don't build it right, it won't produce a great photo.

Unless somebody makes two equally sized sensors with the same native resolution but one with QB and the other one without QB (i.e. a 12MP Bayer sensor and a 48MP QB sensor) and do a side-by-side comparison, you will never know how much effect QB structure has in the actual readout speed.
